Application March .27, 1942, Serial No. 436,442 8 Claims- (Cl. 57-'-125) This invention relates to rings and travelers l for spinning and twisting machines and more particularly to an improved ring traveler for use upon a twister frame for twisting laments together to form a ply strand or cord. The invention has been developed .primarily for use in twisting iine -wire laments' together, to form a ply strand or cord.

In twistingwire laments it has been cusf tomary heretofore to twist the filaments on a stranding machine in accordance with conventional practice of forming strands or cords in the cable industry. 'Ihe use of textile equipment for the purpose of twisting Wire laments has not been considered feasible because of the different characteristics of the metal filament as compared with textile yarns or threads. We have found that strands can be satisfactorily twisted from wire filamentsv with textile equipment by providing aspecially constructed ring traveler. Essentially the invention resides in a ring traveler having means associated therewith for providing a relatively large curvature on that portion of the traveler which is engaged by the wire lilaments, and which is also constructed to direct the lament to one side of the axis of thel spinning spindle.`

A mong the objects of our invention are t provide means whereby wire filaments may be twisted on conventional textile twisting equipment; to provide a ring Atraveler for conventional textile equipment which produces the minimum distortion on the twisted strands; to provide a ring traveler which may be easily associatedy with conventional textile equipment and which will thereby permit the stranding of wire laments; and, to provide a ring traveler for wire strands which may be easily and economically constructed. These and other objects-and advantages will appear more fully in the following detailed description when considered in connection with the accompanying drawing in which:

Fig. l is a perspective view, partly in section, and diagrammatically illustrating a portion of a textile twisting machine incorporating features oi our invention;

Fig. 2 is a perspective view of a ring traveler illustrating in detail the principal embodiment of the invention;

Fig. 3 is a front elevational View thereof; and,

Fig. 4 is a perspective view of a modified form of a ring traveler.

With reference to the drawing and in particular to Fig. 1, our invention is illustrated diagrammatically to include portions of a conventional textile twisting machine. As a source of supply, a plurality of spools II, I2 and Il are suitably supported by the frame of a conventional textile twisting machine. Each of these 'spools retains a supply of wire laments I4. For

purpose of illustrating the invention, three supply spools are shown from which three wire laments are withdrawn to provide ultimately a wire strand formed of the three laments. It is'to be understood, however, that two or more lilaments may be twisted together to form a ply strand and that such ply strands may be subsequently twisted together to form a cord.

Below the supply spools II, I2 and I3 is positioned a guide strip I 5 having an aperture- I6 extending therethrough. The three laments I4 are guided through the aperture I6 to form in effect a plurality of filaments associated in substantially parallel relationship. Good results vhave been obtained by twisting steel wire laments having a gaugeof .0059 inch. A positive feed mechanism is provided for the purpose of moving the wire at a xed and uniform rate. This means lcomprises a pair of shafts I1 and I8 to which are secured multiple grooved pulleys I9 and r2l), respectively. One of the shafts I1 or I8 is driven at a constant rate of speed by conventional means not shown. Each pulley I9 and 20 is provided with iive grooves so as to permit the parallel associated laments I 4 to form four complete belts or reaches around the pulleys I9 'f and 2li. These plurality of Wrappings around the pulleys I9 and 20 provide adequate surface contact with sufficient tension to insure a uniform drive movement of the wire fllaments. Leaving the last groove in the pulley 20, the wire laments extend upwardly and pass' around a sheave 2l rotatably mounted on a pin 22 extending from an arm 23 attached to a rod 2l. The rod 24 is, in turn, supported by some vpart of the frame of the conventional textile twisting machine.

.Positioned directlyA below the sheave 2| is a spindle 25 supported by a bearing in a base plate 26 and capable of being driven by means oi' a pulley 2'I secured to the spindle. The spindle 25, its supporting means and drive are constructed entirely in accordance with conventional textile machinery construction. A spool 28 is shown positioned on the spindle 25. A conventional ring rail 29 is positioned above the base plate 26 and is adaptable for vertical movement. A ring 3u vis attached in nxed relationship with the ring rail 29 concentrically with the spindle 25.

Associated with the ring 30 is a traveler 3|. This traveler is shown in particular-in Figs. 2 and 3. Essentially the traveler comprises a cliplike member having return bent portions 32 and 33 at oppositeends of the clip member. As thus far described, the traveler is of conventional construction. Attached to the face of the traveler is a tubular member 34 of arcuate shape and se-v cured diagonally to the face of the traveler by means of a soldering or brazing operation. The diagonal position of the tube 3| is shown particularly in Fig. 3. The angle 35 with which the tube is positioned relative to the traveler is such that the strand 36 formed from the twisted laments Il will be directed to a point representing the mean distance between the empty and the full capacity of the spool 28. It is preferable that the tube 34 should have as large a radius as possible consistent with the associated equipment.

We have found that good results can b'e obtained by maintaining a radius to the center of the tube of approximately 1*; inch. It is desirable, however, that this radius should not be less than 116 inch. l

Fig. 4 illustrates a modified form of a ring traveler. In this modication the path of curvature for the strand 38 is embodied in the structure of the traveler itself. Essentially the traveler comprises a clip-like member 31 having return bent portions 38 and 39 at opposite ends of the clip member. At one side at the toD of the clip member is an upturned portion 40 which forms a channel having a smooth radiusextending along the top of the clip member as viewed vfrom its front face. Near the bottom of the clip member 31 and at the side opposite the upturned portion l0 is an arcuate out-turned portion 4|. The combined eiiect of the clip member 31 with the out-turned portion 4| and upturned portion 40 is such that a smooth diagonal channel is formed extending across the clip member 31 for receiving the strand 36 and for changing its direction of travel in an arcuate path.

As thus shown and described, it is believed ap parent that we have provided a novel and efficient traveler which in combination with conventional textile equipment makes it possible to twist wire, glass, and other non-textile filaments without setting up undue stresses in the filaments. The traveler however may also be used to advantage upon textile filaments, and while we have shown a preferred embodiment of the invention, it is to be `understood that it is susceptible of those modications, which appear obviously within the spirit of the invention and as dened in the scope of the appended claims.

Having thus described our invention, what we claim and desire to protect by Letters Patent is:

1. In combination with a spinner or twister ring and spindle, a ring traveler adapted to slide u'pon said ring and provided with a lament receiving channel that extends lengthwise of the travelerV throughout a substantial portion of the length of this traveler in a slightly diagonal direction.y
